Outgoing server should be SMTP, not POP3. You also have to activate SMTP port on Optimum (mostly port 25 is used), see this help:Optimum
Most operators in Europe (don't know how is it in USA) also block all SMTP servers and you have to use SMTP server from operator, not from email provider.

I have been frustrated with this setup as well on a few different Android phones, tablets.

My solution finally...

smtp2go.com

I was only able to get email outgoing while on WiFi and not on 3G. Discovered this during a power failure one night. When I changed outgoing smtp to smtp2go.com, I was able to send email through my Eastlink account with no more hassles.

Eastlink could not help me....
Samsung could not help me....

Why is this so friggin difficult to set up on these new phones. I thought technology was supposed to advance......

It's not the phone or Android. It's the ISP that provides your email. Most of them prevent users not on their network from using their SMTP servers as an antispam measure. Some of them allow use of their SMTP server with authentication but you'd need to configure your SMTP servers properly for whatever method of authentication they're using.
